Reconstructing the Iglói system: historical insights and current relevance for distance running

Contemporary distance running training again heavily focuses on controlled longer and shorter aerobic intervals for improving lactate threshold speed (vLT2). From Iglói's system, re-adaptable elements include race speed-specific but controlled short intervals for aerobic conditioning, combined with harder repetitions, alongside the use of active recoveries and "flush" or recovery sets to enhance lactate shuttle mechanisms. Equally important is the emphasis on economic running form at different parts of the race, supporting both efficiency and tactical readiness.
